S45C-500x500

1045 is a medium tensile low hardenability carbon steel

1045 Carbon Steel , S45C, 1191, ASSAB 760, EN9, C45, 45C

Typical applications are: Axles Various, Bolts, Connecting Rods, Hydraulic Clamps and Rams, Pins Various, Rolls Various, Studs, Shafts, Spindles etc.

Flame or Induction Hardening
Heat as quickly as possible to the austenitic temperature range (820 oC – 860 oC) and required case depth followed by an immediate water or oil quench, depending upon hardness required, workpiece size/shape and quenching arrangements.

Following quenching to hand warm, most components should be tempered at 150 oC – 200 oC to remove quenching stresses in the case. This will have little effect on case hardness.
